DESCRIPTION
VRK81B100CS is designed to meet the fast load
transients required by AMD 64-bit processors
and is fully compliant with the latest AMD64™
processor power specifications. High efficiency of
85% at full load for reduced power dissipation to
simplify system thermal management. Packaged in
a compact design, VRK81B100CS is ideal for use in
a wide variety of server applications.
This product is a direct replacement for
VRK81B080CS.
